Course content

This course will focus on relations between geomatics sub-disciplines, geodesy, photogrammetry (measurements in pictures) and GIS, with a final goal of producing maps with modern technologies. The studied methods are not just limited to the production of geographic map data, but apply generally for the construction of 3D objects from images.
A primary Geodesy task is to define the map coordinate system. Coordinate axes are not visible in the terrain but are realized through coordinates for a set of control points, preferably bolted to bedrocks. Before mapping an area, GPS/GNSS measurements are used to establish networks of control points with millimeter accuracy. The control points are marked in order to be recognized in images. In the photogrammetry part of this course, drones/RPAS (Remotely Piloted Aircraft Systems) can be used to take images of a test field. The overlapped images will be geo-referenced and linked together to spatial stereo models. From the models, 3D data for GIS or BIM can be produced. Geometric accuracy estimates will be made for all phases, from the GPS measurements to the final 3D data processing.
The content of this course is under revision, due to changes of lecturers. The topic reliability analysis might be moved down from the course TBA4245 to this course. The reliability analysis is closely linked to the topic estimation in this course, because the accuracy measures of the estimated coordinates and heights are calculated by reliability analysis, also to check that they are within the tolerances of the Norwegian Geodata standard. The reliability analysis will in that case replace parts of the physical geodesy.

Learning outcome

Knowledge:
After this course, the students should have knowledge of:
- Centeral coordinate and height reference systems which are in use in Norway and internationally
- Geoid, geoid height model, deflection of the vertical and transformations of heights between different height systems
- Observation techniques, observation equations and data processing when using the GNSS for geo referencing
- Methods of mathematical statistics and least squares estimation applied on tasks within geomatics
- Aerial and perspective transformations, reconstruction of stereo taking, planning of aerial photographing, and also aero triangulation
- Cameras and camera calibration
- Digital photogrammetry

Skills:
After this course, the students are able to:
- Work and use GNSS equipment for high accuracy static measurements and post processing GNSS computations
- Calculate coordinates and heights in reference systems used in Norway, by using GNSS equipment
- Carry out analysis of accuracy and precision on measured and calculated coordinates and heights
- Reconstruct terrain coordinates from image coordinates and transform the coordinates between 3D coordinate systems
- Carry out collection of data (by measuring on the photographs) and calculations for aero triangulation.


General competence:
After this course, the students can:
- Understand both basic and advanced terms and methods within geodesy/land surveying, satellite geodesy (GNSS) and photogrammetry, and also their mathematical and statistical basis
- Understand and use professional terminology within the discipline
- Work independently and in team and take the necessary initiatives
- Identify common fields between this discipline and other professional disciplines and be open for interdisciplinary approach and cooperation.

Learning methods and activities

Further on evaluation

Portfolio assessment is the basis for the grade in the course. The portfolio includes an final written exam (70%) and evaluation of 2 exercises, each counting 15% (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. If there is a re-sit examination, the examination form may be changed from written to oral. For a re-take of an examination, all assessments during the course must be re-taken.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
